In this blog, we’ll overview the different methods and types of teeth whitening so you can understand your options. We’ll cover in-office power whitening, take-home whitening trays, whitening strips, toothpaste, rinses, gels, and more. By the end, you’ll know how to choose the best teeth whitening treatment for your needs and budget.

Professional In-Office Whitening

In-office power whitening is performed at the dentist’s and provides the fastest, most dramatic results in only one visit. A hydrogen peroxide-based whitening gel is applied directly to the teeth and then activated by a specialized light. The light speeds up bleaching to whiten teeth several shades in an hour.

Custom take-home trays are also filled with a bleaching gel and provided to the patient to continue whitening at home. With the combined power of in-office and take-home systems, teeth can become up to 10 shades whiter.
In-office systems cost more but whiten more intensely in less time. It includes methods like Laser teeth whitening.

Take-Home Whitening Trays.

Take-home whitening systems involve wearing custom-fitted plastic trays filled with a hydrogen peroxide-based bleaching gel for 1-2 weeks or longer. Trays should be worn for 1-2 hours daily, with many offering overnight wear. The trays fit over teeth to keep the whitening agent in contact with stains.

Results are seen in a week or two, with teeth becoming lighter shades. Take-home kits allow you to whiten at your own pace and typically cost less than in-office treatment. For optimal whitening, many patients use take-home trays after an in-office session.

Whitening Strips

Whitening strips consist of thin, flexible plastic strips coated with a whitening gel. Name brands like Crest feature no-slip designs that temporarily adhere to the front teeth for easy application. The peroxide gel stays against teeth to lift stains and bleach from the enamel.

Strips are disposable and used for 30 minutes 1-2 times daily. They gradually lighten over two weeks of consistent use but may cause gum irritation. Generic strips are cheaper, while named brands provide the best results. Strips only whiten and bleach the exposed tooth surfaces.

Whitening Rinses

Whitening mouthwashes feature low concentrations of hydrogen peroxide or carbamide peroxide. When swished in the mouth for 60 seconds daily, the solution comes into contact with teeth to lift some stains and discoloration. However, whitening rinses produce minimal results compared to trays and strips.

A whitening rinse is best for minor upkeep between professional treatments. Use for two weeks, then take a break before restarting. This helps avoid mouth irritation and tooth sensitivity from prolonged use.

Whitening Toothpastes

Whitening toothpaste includes polishing agents and chemicals like hydrogen peroxide to buff away surface stains each time you brush. This provides a bit more brightness but cannot penetrate deep stains. Toothpaste maintains results from other whitening systems but doesn’t significantly bleach.

Look for toothpaste with the ADA Seal of Acceptance to ensure safety and effectiveness. Whitening pastes should still contain fluoride for cavity protection.
Results appear gradually over 4-6 weeks when brushing twice daily.

Whitening Gels

Thicker gels offer more intense bleaching than whitening toothpaste since they adhere and penetrate better. Gels contain 10-22% carbamide peroxide that sits on the teeth for up to an hour. Brush on a thin layer, let it work, then rinse. Use once daily for the duration directed on the product.

Gels provide brighter teeth within 2-3 weeks of application. However, they can irritate sensitive teeth and gums. Consult your dentist before DIY use, especially with very high peroxide concentrations.

Other Whitening Options

Natural whitening options like charcoal or baking soda lack peroxide for bleaching but help buff stains on enamel. Be wary of abrasiveness damaging enamel over time. Commercial lighting pens apply hydrogen peroxide directly to stains. Use cautiously to avoid gum burns.
